“There are a fair number of predatory attacks by grizzly/brown bears which stalk their prey.”
I think you’re confusing territorial defense and opportunistic feeding with predatory behavior.
How do you distinguish between the two, when the victim/s did not survive?
Grizzly bears often cover up their prey to feed on later. Easier to pull appart and eat after it has decayed a bit...
A number of the attacks are listed as predatory by the investigating authorities.
